BUTTON.

. Specification of Letters Patent.

Patented April 10, 1906.

To all whom it may concern.-

Be it known that I, WILLIAM HAMILTON FORSYTH, a subject of the King of Great Britto be a full, clear, and exact description the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention, which relates to buttons, consists in improvements therein, as set forth below.

In a button made in accordance with this invention the shank, which is made in one piece with the head, is a truncated cone, decreasing in diameter from the back of the head to the end of the shank, which comes next the fabric when the button is attached thereto. The erforations in the head, through which t e attaching-thread is sewed, open into inclined channels, which approach each other as they extend back in the shank, the rear part of which is tubular. The thread by which the button is secured to the fabric is passed through the channels in the button and through the fabric.

Referring to the accompanying drawings, Figure 1 represents a face view, and Fig. 2 a section, of a button made in accordance with this invention. Fig. 3 is a back view, and Fig. 4 is a sectional view illustratin the attachment of the button to a piece 0 cloth or other fabric.

The tubular shank a, which is made in one piece, of vulcanite, bone, or other suitable substance, with the head 1), extends back therefrom as a truncated cone, decreasing in diameter from the back of the head to the rear end of the shank, which lies against the fabric 0, as seen more 'articularly at Fig. 4. The passages or channe s dfor the thread e are inclinedtoward one another as they extend back in the shank. This disposition of the thread-passages approaching one another as they extend back enables the shank to be buttonholes in made tapered, as shown. The tapered form" enables the shank to be kept down to a sizwhich does not undul; spread and kee open arments and other abrics. The shank can e kept down to a neat and convenient size and still reserve sufficient stren th for secure attac ment and with-' stan ing strain in use.

In sewing the button onto a fabric the thread, as seen at Fig. 4, is passed through the fabric and throu h the channels d and over the bridge-piece which separates them.

What I claim, and desire to secure by Letters Patent, is-

1. The herein-described one-piece button consisting of a head rovided with a peripheral bead, a depressed upper surface, a tapering shank prqecting from the back of the head, and provided with thread-openings, a bridge-piece formed between the thread-openings, the latter converging within the shank, said brid e-piece being on a plane below the depresse up er surface of t e button-head, and the shan being hollow below the bridge, essentially as described.

2. A one-piece button comprising a head, a ta ering shank projecting from the back of the ead and provided with thread-openings, a bridge-piece formed between the thread- 0 enings, the latter converging within the s ank, said bridge-piece bein on a lane below the upper surface of the uttonsad, and the shank being hollow below the bridge.

3. A oneiece button consisting of a head, a tapering s ank projecting from the back of the ead and provided with thread-openings, a bridge-piece formed between the thread- 0 enings, the latter converging within the s ank, and the shank being hollow below the bridge, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.

WILLIAM HAMILTON FORSY'IH.
